Off-load tap-changer driving mechanism 5. High quality of the welding seams is guaranteed by tests with penetrating agents in a special test field and by testing with over pressure of 40 kPa. Our production is maximally extended — we manufacture the full trato of elpeom immersed distribution transformers with rated power from 25kVA up to 10 kVA. The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board.

Type tests are performed on each transformer type. These are performed upon special request of the customer.

Axial bolts do the axial tightening of the windings. Nowadays we have control laboratories for incoming, current and outgoing control of the materials, used in the production, as well as testing laboratory for routine and type testing of the elprmo.

At the bottom the walls are welded to the tank bottom. Elpom more than 10 years now the plant has an established and certified quality management system acc. Contemporary automated lines cut the steel sheets delivered in rolls longitudinally and transversally.

These include temperature rise test and lightning impulse test. In the upper part the walls are welded to a flange frame to which the tank cover is bolted. China dry trxfo kva China transformer w China transformer kva toroid.

Not exactly what you want? They have an insulation of cable paper or enamel resistant to hot transformer oil. El;rom is done in protective atmosphere Ar-CO2.

Dial type – thermometer with alarm contacts over kVA. One decade later the plant achieves significant development, it is renewed technologically, expands and the production range is extended.

Dehydrating breather for TM series The neutral terminal of the LV winding for all the transformers is brought out on the transformer cover through a separate bushing that is designed for the full rated current and is insulated for the highest voltage of the LV system.

The fitting elements bolts, nuts, washers etc. For each rated power we offer different series, depending on the no-load and load losses. China for transformer China transformer kva rating China transformer.

The LV winding is situated at the core limb and is foil cylindrical type made out of profiled section copper for the ratings including kVA and out of copper foil for ratings kVA and above. Thus a sufficient thickness of the protective coating of min. You, our customers know well that without solid foundation and clear goals there is no development, and we have both.

Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional. We also have another advantage — the especially for us designed software for optimal design of transformers. The windings are of cylindrical type situated concentrically on the core limbs. The transport carriage with wheels is fitted to the tank bottom allowing bi-directional movement of the transformer.

The thickness of the coating is increased depending on the operational climatic conditions.

TANK The standard type of the transformer tanks is rectangular a welded structure with corrugated walls made out of cold rolled steel sheets with low carbon content. We have a developed and introduced automated system for management of the purchase orders, management system for the technical documentations and management system of the material base of the plant.

The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized. The optimal design of eprom windings and employment of most contemporary technology, the optimal selected cooling ducts, properly dimensioned insulation, effective tightening in radial and axial direction result in a high electrical, thermal and dynamic withstand capability according to the requirements of Eplrom.

The active part is lifted along with the cover by the lifting eyes situated on it. The HV winding is a multi-layer one for the lower ratings and two- or four-section multi-layer, block-coils or continuously wound disk winding for the higher ratings. Buchholz relay over kVA We can now shorten the production period to a maximum and this way — spare your time.

Rating plate and diagram 4. The quality procedures, according to ISO We have special design and trqfo departments, thereby the production cycle becomes fully closed — from the design of the transformer to its assembly, in accordance with the requirements of the end customer and every related national and international standard.

The maximum production capacity of the plant has been reached before the end of the past century — 10 pieces of transformers are being manufactured annually. The outer surfaces are coated by several layers of anti corrosion primer and finished by high quality alkyd enamel.

Contemporary lines for automatic corrugation and plasma welding produce the tank walls. The active part is fixed to the tank cover and is supported by the tank bottom.

The combinations of LV foil winding and multi layer HV winding results in a significant reduction of the axial electrodynamics forces at short circuit for the high ratings. Using the scroll is also considered to be a consent!
